This invention relates to the driving of a printing press. The principal objects thereof are to place the motor in such a position that it is entirely out of the way of the operator II and can be attended to more easil than under resent conditions and is readily accessible or the various adjustments, the application of lubricants and the control of the running of the press.

Reference is to be had to the accompanying; drawings in-which ig. 1 is a side view of a printin press, or

embodia unit thereof, showing a preferr ment of this invention;

15 mg. 2 is an end view of the same;

Fig. 3 is a plan thereof; and

. Fig. 4 is a sectional view on the line 44 of Fig. 2.

Printing presses are frequently run by electric motors and it is customary to place the motor either at the floor level of the press or in a pit built below the floor level. Inone case it is necessary to rovide the pit at considerable expense and in the other case to which, as time goes on, is more and more desirable. There is little space available. In

both cases also the location of the motor involves difiiculty in tting at it and keeping it in condition and also attendin to some parts of the press. It is for avoi ing these difliculties thatthis invention is made.

I "have shown theinvention as applied to a press of the usual type involving a pair of plate cylinders 10, a pair of impression cylinders 11 and means for idin the web throu h the couples from t e we roll 12 to a gui e roll 13 from which the web is led from the press. The usual inking mechanisms 14 are shown. Y

-. Ordinarily this press would be run from a motor below where it would either occu y valuable floor s ace ornecessitate a pit. n-

stead of either provide the frame 15-with severaluprights 16,0n which is located a top 17 made strong and rigid and on thisI rovide an adjustable plate or rails 18 w ich constitutes the base for the usual operating motor 19.

On the shaft of the motor is a sprocket 21 end or stud 24 of one o the cylinders. Also provide room on the floor of the press room which through a chain 22 transmits wer to a sprocket 22. v This latter sproc et is loosely mounted throu h a sleeve 23 on the loosely rotating on the sleeve 23 is a gearor pinion 25 having a hub 26 to which is keyed the sprocket wheel 22 so that they are free to rotate together independently of the. cylinder on the end of which they are located. This gear 25 meshes with a gear 27, whichis fixed tothe end of an adjacent cylinder 11 and drives it positively from the motor. The several impression and late'cylinders'are oon+ nected up to each ot er by gears 28 so that power is transmitted from one to another.

11 this way all the cylinders are positively driven from the motor. The result is a comact and even drive for the print' press. t reduces'the cost of building the oundation for the motor by eliminating the nec'essity of a pit or reduces the space which the press occupies on the floor. At the same time it provides a rigid sup ort for the motor and locates the motor at a at its usual distance from the cylinders which it drives.

.Although I have illustrated and described only a single form of the invention-I am aware of the fact that modifications can be made therein by any rson skilled inthe. art and it can be applied to many types of presses without departin from the scope of the invention as expresse in the claims.

Therefore, I do not wish to, be limited to all the details of construction herein shown and I described, but what I do claim is 1. In a printing press, the combination of a frame, printing couples supported thereby, said frame extending above the level of the printing couples, an electric motor located on the extension of the frame at a point above the level of the printing couples, and having its shaft parallel with the axles of the printing couples, a sprocketwheel rotated by the motor shaft, a chain connected with said sprocket wheel and means for driving one member of the printing couples directly by said chain.

2. In a printing press, the combination with asupport located above and to'one side of the printing couples, of a motor carried by said support, a driving chain operated by the motor, one member of the rinting couples having a stud thereon, a s eeve on 3. In a printing press, the combination with a motor, and a driving chain operated by the motor, of printing couples, one memher of which has a stud thereon, a sleeve on the stud, a gear loosely mounted to rotate on the sleeve, a gear fixed to said gear in a position to be driven by said chain, and a gear on the member of another rinting couple meshing with the first-named gear to be driven thereby.

4. In a printing press, the combination of a printing couple, one member of which has a stud thereon, a sleeve on the stud, a gear loosely mounted to rotate on the sleeve, a driving wheel fixed to said gear, a motor connected with .the drive wheel for operating it, another printing couple, and a gear on one member of the other printing cou le meshing with the first-named gear to driven thereby.

5. In a rinting press, the combination with the printing couples and inking mechanism therefor, a frame for supporting the couples, said frame extending'above the level of the rinting couples, and a support thereon at.1ts top and ad'ustable thereon," of a motor mounted in sai support above and to one side of the printing cou les, and a chain extending direct from said motor to one member of a printing couple for 0 rating all the members of the printing coupl e s In testimony whereof I have hereunto af fixed my signature.
